Detailed Description
Primary objective To investigate the effect of anaesthetic technique on:
Short term: time to start of adjuvant chemotherapy in patients planned for RIOT Long term: Time to recurrence (TTR) at 3 years. (please see section 4.2 for details) Secondary objectives 0-30-day postoperative morbidity Length of hospital stay and days at home for 30 days (DAH-30) Adverse events related to oncological treatment (chemotherapy, radiotherapy) Study Subjects Patients with stage I-III colorectal cancer (stratified to stage and type of cancer) scheduled for upfront curative surgery.
Study design Prospective, multicentre, international, observational, pragmatic study Planned sample size 10000 patients from > 200 centres (minimum 40 patients/centre) Inclusion criteria Age > 18 years ASA I-III Scheduled for elective (planned) colorectal cancer surgery for stage I-III (open or minimally invasive) Signed written informed consent when requested by the local Ethics committee Exclusion criteria Uncontrolled renal or liver disease, restrictive (limiting mobility) heart failure or ischemic heart disease (ASA IV-V) Speech, language or cognitive difficulties precluding signing informed consent to participate Stage IV colorectal cancer Primary Outcomes Time to return to intended adjuvant (postoperative) chemotherapy (number of days after surgery) Time to recurrence (TTR) of cancer at 3 years (please see section 4.2 for details) Secondary outcome Percentage of complications within 30 days of surgery as graded by the Clavien-Dindo classification Other adverse events not included in the C-D classification within 30 days Length of hospital stay defined as days from index surgery to arrival at original living facility Days at home for 0-30 days (DAH-30) after index surgery Adverse events related to oncological treatment
